Breeding for Slow‐Darkening, High‐Yielding, Broadly Adapted Dry Bean Pinto ‘Kimberly’ and ‘Shoshone’

Pinto dry bean (Phaseolus vulgaris L.) ‘Kimberly’ (Reg. No. CV‐283, PI 653256) and ‘Shoshone’ (Reg. No. CV‐284, PI 653257) were developed at the University of Idaho‐Kimberly Agricultural Research and Extension Center. Both were released by the Idaho Agricultural Experiment Station on 12 Apr. 2007. Kimberly is a full‐season (100 d to maturity) and Shoshone is an early‐ to medium‐maturing cultivar. Both have light‐colored and slow‐darkening pinto seed. Both are high‐yielding, widely adapted cultivars and possess the bc‐3 and I genes imparting resistance to all strains of Bean common mosaic virus and Bean common mosaic necrosis virus (an aphid‐vectored potyvirus) and to rust [caused by Uromyces appendiculatus (Pers.) Ung.]. Both also have moderate to high levels of resistance to heat and drought. However, both are susceptible to soil zinc deficiency and manganese toxicity.
